Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if advCalendar extension is installedCheck TYPO3 extension manager or list of installed extensions for 'advcalendar' or 'advCalendar'Affected if The extension appears in the list of installed extensions
-
Determine the installed version of advCalendarView the extension details in TYPO3 extension manager, check the ext_emconf.php file version, or query the extension version via TYPO3 backendAffected if Version is 0.3.1 or earlier, or version cannot be determined but extension is present
-
Verify the extension is enabled and loadedCheck the extension configuration status in TYPO3 backend or examine theTYPO3 system for active extension loadingAffected if Extension is marked as active or loaded in the TYPO3 installation
-
Confirm exposure to unauthenticated requestsReview the TYPO3 frontend configuration and whether the advCalendar plugin is rendered on any accessible pages without authentication requirementsAffected if The extension functionality is accessible to anonymous or unauthenticated web visitors
A user is affected if the advCalendar extension version 0.3.1 or earlier is installed and enabled in their TYPO3 environment, exposing the SQL injection vulnerability to remote attackers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate advCalendar to the latest patched version, or if unavailable, disable the extension. Implement parameterized queries or proper input sanitization on all user-controlled parameters in the extension code.
